  Now, the operation of the ultrasonic diagnostic apparatus 1 of this example will be described based on the flowchart of FIG. First, in step S1, the operator holds the arm Ar of the subject to be examined between the first ultrasonic probe 23 and the second ultrasonic probe 24 as shown in FIG. The first ultrasonic probe 23 and the second ultrasonic probe 24 are arranged at the examination site. The first ultrasonic probe 23 is in contact with one body surface of the arm Ar of the subject. The second ultrasonic probe 24 is in contact with the other body surface of the subject's arm Ar opposite to the one body surface. The operator slides the jaw 22 to adjust the distance between the first ultrasonic probe 23 and the second ultrasonic probe 24, and transmits and receives the transmission / reception surface 23 a of the first ultrasonic probe 23 and the second ultrasonic probe 23. The transmitting / receiving surface 24a of the ultrasonic probe 24 is brought into close contact with the surface of the arm Ar.

  Next, in step S <b> 2, the distance measurement unit 25 calculates the distance d between the first ultrasonic probe 23 and the second ultrasonic probe 24. The distance d is a distance between the transmission / reception surface 23a and the transmission / reception surface 24a. The distance d calculated by the distance measuring unit 25 is input to the echo data processing unit 4 via the probe cable 26.

  The calculation of the distance d may be performed, for example, when an operator inputs a distance measurement instruction through the operation unit 7. In addition, the calculation of the distance d may be performed every required time after step S2 after the distance measurement instruction is input, and the information on the distance d may be updated.

  Next, in step S3, ultrasonic transmission / reception is performed by the first ultrasonic probe 23. In step S <b> 3, the transmission / reception beamformer 3 performs control so that ultrasonic waves are transmitted and received only by the first ultrasonic probe 23. When an ultrasonic echo signal is received by the first ultrasonic probe 23, the first B-mode data creation unit 411 creates first B-mode data based on the echo signal.

  Next, in step S4, the transmission / reception beamformer 3 switches from transmission / reception of ultrasonic waves by the first ultrasonic probe 23 to transmission / reception of ultrasonic waves by the second ultrasonic probe 24. Accordingly, in this step S4, ultrasonic waves are transmitted and received only by the second ultrasonic probe 24. The second ultrasonic probe 24 transmits and receives ultrasonic waves on the same cross section as the first ultrasonic probe 23. When an ultrasonic echo signal is received by the second ultrasonic probe 24, the second B-mode data creation unit 412 creates second B-mode data based on the echo signal.

  In step S5, the combining unit 42 generates combined image data. The combined image is an image displayed on the display unit 6 in step S6 described later. As shown in FIG. 6, the combined image BI is an image in which a first B-mode image BI1 based on the first B-mode data and a second B-mode image BI2 based on the second B-mode data are combined. It is. The combining unit 42 combines the first B-mode data and the second B-mode data so that the first B-mode image BI1 and the second B-mode image BI2 are the first B-mode. Data of a combined image that is combined in the depth direction of the subject in the image BI1 and the second B-mode image BI2 is created.

  In the combined image BI, the first B-mode image BI1 and the second B-mode image BI2 are combined on the side opposite to the body surface side of the subject. The combining unit 42 is configured so that the length in the depth direction of the subject in the combined image BI becomes the length D corresponding to the distance d obtained by the distance measuring unit 25. The data and the second B-mode data are synthesized. When the information on the distance d is updated, the combining unit 42 uses the latest information as the distance d.

  Based on the distance d, the combining unit 42 sets a range in the depth direction of the subject of the first B-mode data and the second B-mode data used for creating the combined image data. For example, when the length D1 in the depth direction of the subject of the first B-mode image BI1 and the length D2 in the depth direction of the subject of the second B-mode image BI2 are the same length (D1 = D2 , D = D1 + D2), the combining unit 42 creates the combined image data using the first B-mode data and the second B-mode data in a range corresponding to the length of d / 2. .

  Next, in step S6, the display processing unit 5 causes the display unit 6 to display a combined image BI for a required cross section of the subject, as shown in FIG. 7, based on the combined image data.

  Note that, when the frame of the combined image BI is updated, the processes in steps S3 to S6 are repeated.

  According to this example, on the one body surface side of the arm Ar of the subject, ultrasonic waves are transmitted and received by the first ultrasonic probe 23 to acquire an echo signal. In addition, on the other body surface side opposite to the one body surface, ultrasonic waves are transmitted and received by the second ultrasonic probe 24 to acquire an echo signal. Therefore, an echo signal stronger than before can be acquired from one body surface side to the other body surface side in the arm Ar of the subject. And since the combined image BI consisting of the first B-mode image BI1 and the second B-mode image BI2 created based on this echo signal is displayed, the operator can view both the bone diameter and the soft tissue. It is possible to observe the combined image BI with better image quality than before.

  Next, a modification of the embodiment will be described. First, the first modification will be described. As shown in FIG. 8, the display processing unit 5 displays on the display unit 6 a superimposed image I in which a medical image MI acquired in a modality different from that of an ultrasound diagnostic apparatus is superimposed on the combined image BI. Display. The medical image MI is an X-ray image acquired by, for example, an X-ray apparatus. The medical image MI may be an X-ray CT image acquired by an X-ray CT apparatus, an MRI image acquired by an MRI apparatus, or the like. The data of the medical image MI is stored in the storage unit 9. The display processing unit 5 adds the data of the medical image MI read from the storage unit 9 and the image data of the combined image BI to create image data of the superimposed image I.

  The medical image MI is an image of the same part in the subject as the combined image BI. The data of the medical image MI and the image data of the superimposed image I may be added after being subjected to alignment processing. In this case, the ultrasonic diagnostic apparatus 1 may include a position sensor (not shown) for detecting the positions of the first ultrasonic probe 23 and the second ultrasonic probe 24. The positioning process may be performed using position information detected by the position sensor.

  Next, a second modification will be described. In this second modification, the speed of sound of the body tissue of the subject is measured. As shown in FIG. 9, the echo data processing unit 4 includes a sound speed calculation unit 43 in addition to the B-mode data creation unit 41 and the coupling unit 42. The sound speed calculator 43 is an example of an embodiment of a sound speed calculator in the present invention.

  The measurement of the sound speed in the second modification will be described based on the flowchart of FIG. First, in step S <b> 11, the transmission beamformer 3 causes the first ultrasonic probe 23 to transmit ultrasonic waves. Next, in step S <b> 12, the ultrasonic wave transmitted by the first ultrasonic probe 23 in step S <b> 11 is received by the second ultrasonic probe 24. Incidentally, at the time of transmission / reception of ultrasonic waves in steps S11 and S12, as described above, the first ultrasonic probe 23 and the second ultrasonic probe 24 are arranged so as to sandwich the arm of the subject. (See FIG. 5).

  In step S12, when an echo signal is received by the second ultrasonic probe 24, in step S13, the sound speed calculation unit 43 calculates the sound speed v in the living tissue of the arm Ar of the subject. The sound velocity calculation unit 43 includes a time t from when the ultrasonic wave is transmitted by the first ultrasonic probe 23 until the ultrasonic wave is received by the second ultrasonic probe 24, and the distance measurement unit. The sound velocity v is calculated based on the distance d measured by 25. As the distance d, the one calculated in step S2 is used. The sound speed calculation unit 43 calculates the sound speed v for each ultrasonic ray (for each ultrasonic beam).

  Next, in step S4, the display processing unit 5 creates sound speed image data based on the sound speed v data for each sound ray calculated in step S3. The display processing unit 5 is an example of an embodiment of a sonic image data creation unit in the present invention. Then, as shown in FIG. 11, the display processing unit 5 causes the display unit 6 to display a sonic image SI based on the sonic image data. The sound speed image SI is a color image having a color corresponding to the sound speed v calculated for each sound ray, for example.

  The sound speed image SI is synthesized with the combined image BI. The display processing unit 5 adds the image data of the combined image BI and the image data of the sound velocity image SI to create composite image data. The display processing unit 5 causes the display unit 6 to display the composite image CI based on the composite image data. The composite image CI is an image in which the combined image BI is transmitted through the background of the sound speed image SI.

  As mentioned above, although this invention was demonstrated by the said embodiment, of course, this invention can be variously implemented in the range which does not change the main point. For example, in the above-described embodiment, the first B-mode image BI1 and the second B-mode image BI2 are combined in the combined image BI so as not to overlap, but the present invention is not limited to this. . For example, as shown in FIG. 12, in the combined image BI, a part of the first B-mode image BI1 and the second B-mode BI2 overlap on the side opposite to the body surface (the deep side of the subject). It may be. In FIG. 12, the combined image BI has an overlapping portion having a length D12. The combining unit 42 adds the first B-mode data and the second B-mode data at the overlapping portion.

  In the above-described embodiment, the combined image data is raw data, but the combined image data may be image data. That is, combined image data may be created using image data. In this case, as shown in FIG. 13, the display processing unit 5 has a coupling unit 52. The echo data processing unit 4 may not include the coupling unit 42.

  The display processing unit 5 includes a B-mode image data creation unit 51 and an image display control unit 53 in addition to the combining unit 52. The B-mode image data creation unit 51 includes a first B-mode image data creation unit 511 and a second B-mode image data creation unit 512. The first B-mode image data creation unit 511 scans the first B-mode data to create first B-mode image data. The second B-mode image data creation unit 512 scans the second B-mode data to create second B-mode image data.

  The combining unit 52 creates combined image data (image data) in the same manner as the combining unit 42 from the first B-mode image data and the second B-mode image data. Then, the image display control unit 53 displays the combined image BI on the display unit 6 based on the combined image data.
